Nah, not good enough.

Surface winds can vary tremendously from winds even a few thousand
feet above the surface.  A couple of months ago I was flying with a
friend and at anything over 2500 feet above the ground we had a 60+
knot headwind, but surface winds were only in the teens (and from a
different direction, which was a wind shear condition).  We knew what
was happening, and other pilots were reporting the same problem when
landing, but there was no "official" source for wind data that showed
the same conditions.
